It’s all happening. Really. There feels like there’s good stuff on the box every time you switch on. Suddenly things are busy in the crime drama corner, especially at weekends, where Beck – the latest Scandi import – and series two Hinterland/Y Gwyll is bubbling away on Saturday and Sunday nights. But this week, we say goodbye to series three of Ripper Street – sometimes uneven, but in this run it has really hit its stride.

Ripper Street *SERIES FINALE*This third series has been terrific, certainly the best yet, and we reach the finale with a few things up in the air – what is Reid’s fate? Will justice finally be served to Susan? An American journalist is killed in Whitechapel and his exclusive story threatens seismic consequences for numerous Whitechapel residents. With her business empire slipping through her fingers, Long Susan has to contend with some shocking news – and a face from her past who returns to exert their control. As the men of H Division inch ever nearer to the truth about the train robbery, the revelations expose some disturbing home truths, and life-altering decisions have to be made.Friday 18th September, 9pm, BBC1For all our Ripper Street news and reviews, go here
